dell inspiron 600m touchpad goes crazy

ok I have a dell laptop and it works for awhile then the mouse stops working when I try to move the mouse it starts to click things and move crazy it does not function right. I not sure what is the problem I think may be the touch pad has gone bad.

yep i have sort of the same thing sometimes, i have a sony vaio VGN FS515E and when i go to move my mouse it gets stuck and tries to go the other way, i think it may be a hardware issue, or the tracker pad itself but i may be wrong

Problem is the dust around the corners of the pad is confusing the touchpad into going into different directions. Take apart the laptop disconnect the touchpad, which will clear its eeprom , and clean the pad gently with a tissue. Problems are solved. Promise
